"Symbian anti-virus specialist SimWorks announced today that it has identified the first threat able to so severely disrupt the functioning of a Symbian phone that it can no longer be used to make phone calls. Previously identified threats, such as the Skulls trojans, have affected only the higher level functions of a device, not it's ability to make calls".
